Knobs are not working in Virtual Cockpit NGX 738

Hi everyone,

I am using the CP in stable mode. The problem is , when I first jump in to the VC I can push or turn every knob. However once I change the view (i.e. radio stack) and come back to Captain view I cannot touch any button nor knob. I already tried to change my viewpoint by zoom+, zoom- or laterally but no solution.

Is there anybody facing the same problem?

Any help would be highly appreciated.

Thanks in advance ,

Hakan
